TO ALL WHOM IT MAY CONCERN:

Be it known that I, ARTHUR GATES WILSON, formerly of Chicago, Illinois, now of New York city, in the county and State of New York, have invented a new and improved Metallic Oil, Varnish, and Fluid-Tank; and I do hereby declare that the following is a full and exact; description thereof, reference being bad to the accompanying drawings, and to theletters of reference marked'thereon. I

Figure 1 is a longitudinal'section of my improved oil, varnish, and fluid-tank drawn vertically through the centre, the plan of section being indicated by the letters A A.

Figure 2 is a side view otthe adjustable wooden top of my improved tank, showing the hinged cover when partly opened.

Figure 3 is a plan or top view of the adjustable top to my improved tank.

Figure 4 is a plan view of the plain or corrugated bottom on an inclined plane standing. toward the front or outlet, with strainers and tube attached, as seen looking down through the top of the tank.

The object of my invention is to provide a more safe, convenient, economical, and durable receptacle for oils, varnishes, and fluids of all kinds, in stores or warehouses for wholesale and retail purposes, by the improved adjustable top and-'inclined'clevated bottom combined with aperforatedtin'orwire strainer over the outlet,

preventing any thick substance from obstructing the passage; To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

First, as a basis, I use common sheet metal, which I form into the shape of a cylinder, A A, secured together by common seam and solder. I then bind the oylinder A A with bands, as indicated at lines Z N l Z Z Z, also of common metal secured to the cylinder by common solder, or other methods. I then wife the top and bottom 0" O" with heavy wire, in order to strengthen the edges of the cylinder, after which I insert the wooden bottom F, on an inclined plane of one inch slope to every foot in diameter of the cylinder, elevating it two or more inches from the wired edge 0, and securing it in that position by small braces, or other methods, in order that it may be sufiiciently strong-to support the weight of the liquid in the tank. My object in elevating the bottom from the edge 0, as described is to obviate the inconvenience of tipping the tank to draw off its contents when low, and also to prevent saturation by moisture underneath, thus preventing the bottom from rusting, corroding, or decaying. I then insert a plain or corrugated lead or composition lining on the top ot' the wood bottom F, after having secured it to the tube G, which is all securedfast to the sides of the cylinder, thus forming a tank. The object of the tube is to lower the outlet below the bottom sufliciently to more eifectually draw ofi' all the liquid. This done, I cover the top of the tube G with a perforated tin or wire-cloth strainer, H, surrounded at the bottom by the rim n", the object of which is to prevent any third substance or sediment from passing through or obstructing the outlet at n".

At It is a common boss, to brace more firmly the look into the tank.

At B is an adjustable wooden top, made of common deal, so that it can be removed, when necessary, for the purpose of cleansing the tank, and so constructed that it fits tight all round the edges, and rests on shoulders k k, to prevent it from slipping into the tank. When the top, B, rests on the shoulders 7c la, it is countersunk one-half an inch below the wire edge 0'', so that in case of accidental spilling on the top it will not run on the sides of the tank.

At 0 is the squarc-hinged-cover, made also of wood, with the flange P and inverted edges q" q" fastened to the top, B, by common square or strap-hinges, j, the object of which is to aiford convenience for filling the tank.

At E is a swivel, passing through the cover, with a catch underneath, and the shoulder i, which is to more effectually close the cover tight, in order to keep out all dust, and to prevent the evaporation of fluids. I also cover the wood top, B, and the cover, 0, inside and out with boiled glue, or other impenetrable substance accomplishing the same purpose, to prevent saturation of the top by oils or fluids.

Now, having fully described my device,'what I claim as my invention, and desire to secure by Letters liateut of the United States, is

1. The bottom,'F, strainer H, and tube G, all arranged and combined substantially as described and for the purposes set forth. a

2. The detachable head, B, when so arranged within the cylinder A as to have-its upper surface fallbelo the walls of said cylinder to operate in connection with the supplemental cover, 0, substantially as and for the purposes specified.
